As someone who has been there and done that in a few multinationals I would say ignore all these losers have told you. Not one of them knows what they are talking about......harsh but true...... Be confident, be different, understand how the company is organised and how it really operates, think big, think strategic, put yourself into challenging positions, understand your own weaknesses and put them right year by year, find yourself someone really senior to mentor you and bloody well listen to them, don't play politics, never say a bad word against anyone, actively help to develop those below you, and in terms of work always be seen as the one who tells the absolute truth......credibility is everything.....whatever talent you have will take care of the rest.......
